8 Claims. (Cl. 21-24) My invention relates to an apparatus for mixingembalming solutions preparatory toinjection of the same into a corpse.

In the present day practices of embalming dead I :quently spilled on thehands or clothing of the operator or on other objects with objectionableresults. It is very desirableto be able to vary the strength oftheembalming fluid even during the embalming operation, as during suchoperation it is necessary to watch the body for evidence of ill effectsproduced by the embalming fluid which are due primarily to conditions ofthe body previously caused by the nature of the ailment which causeddeath and the fact that the solution has not been properly proportionedto meet the particular condition of the body.

The principal object of my invention is to produce embalming apparatusof the class described of simple form and construction by means i ofwhich the concentrated embalming fluid may be exactly mixed with waterto produce the desired solution and which apparatus may be readilyadjusted during the embalming operation sothat the mixture may be variedas circumstances may require.

Other objects. and advantages will appear hereinafter from the followingdescription and drawing. Referring to the drawing, which is forillustrative purposes only Figure 1 is a diagrammatic sectionalelevation showing an apparatus embodying the form of my invention; and lFigure 2 is a sectional view on line 2-2 of Figure 1.

More particularly describing the apparatus shown in the drawing Arepresents a Jar or reservoir containing the concentrated embalmingsolution; B a water supply fromjthe ordinary pressure water system; C awater motor; D a pump; and E a mixing chamber. The above; mentionedparts are the general features of the apparatus and are used with properconnections for utilizing the pressure of thewater supply by means ofthe water motor to operate a pump which pumps regulated portions of theconcen- A further objection to trated solution to the incoming waterwhere it is introduced into the water stream after which the mixturepasses through the mixing chamber under pressure to a suitableinjectorby means of which the fluid is introduced into the body.

The numeral ll indicates a connection to the citywater supply, notshown. This connection is provided with a conduit I2 through which waterunder pressure is supplied to the apparatus. For the purpose ofautomatically controlling the supply of water through the conduit l2 aneedle valve i3 is provided which engages a seat l4 to shut off suchwater supply as will hereinafter be more fully described. The conduit 12is connected to the valve chest i5 of the water motor C, the conduit l2terminating in a distributing port l6, controlled by a reciprocatingvalve member l1. The valve chest I5 is provided with ports l8 and I9whichconnect respectively with passages and 2| at the ends of a cylinder22, the passage of liquid from the conduit l2 through the ports I! andi9 is controlled by the position of an annular channel 24 in the valvemember Il. As shown in the drawing the position of the channel 24 issuch that fluid from port I5 is discharged through port l8 to passage 20then into the cylinder at the rear of piston 25. The outer ends of thepassages 20 and 2i are in open com-' munication with a conduit 26connected to a diversion valve 21. The introduction of fluid to the rearof the piston, as just above described, causes the piston to move in thedirection of the arrow until it reaches the end of its stroke and duringsuch movement operates mechanism, hereinafter more fully described,which ,moves the valve member ll so that an annular channel 28 which isnow in position to permit flow of fluid from in front of piston to theconduit 26 moves into a position which closes the passage 2|. At thesame time that this takes place a channel 30, in the valve member ll,moves into position so that the passage, 20 is opened and the channel 24moves into position, closing theport l8 and opening the port I9 so thatthe incoming fluid under pressure from conduit l2 passes to the front ofthe piston and moves it in opposite direction to that above described.

The piston 25 is flxed to a piston rod 32 which extends through the endsof the cylinder 22, one

end of the piston rod extending into a pump vided with openings 31 topermit some of the liquid in the mixing cylinder to pass through thepiston as it reciprocates for the purpose of thoroughly mixing the fluidtherein.

The means provided for reciprocating the valve member l1 consists of thefollowing mechanism: Secured to the piston rod 32 is an arm 40terminating at its upper end in a yoke 4| which engages a circularflange 42 on the end of a valve sleeve 43 which reciprocates in thevalve chest 44 of the pump 33. The valve sleeve 43 has the same lengthof reciprocating movement as the piston rod 32 but it is pointed outthat the valve member I1 has a comparatively short movement. To providefor this diflerenceuin movement, the valve sleeve 43 is provided with aslot 45 into which extends a pin 46 on the outer end of the valve memberH, which end of the valve member is slidably received in one end of thevalve sleeve 43. The slot 45 is less in length than the stroke of thepiston rod 32 so that the pin 46 is not engaged by the end of the slot45 until the piston 25 has nearly reached the end of its stroke, atwhich time the end of the slot moves the pin 46 and valvemernber l1 aproper distance to bring the channels 24, 28 and 30 of the valve memberinto proper relation with the ports and passages of the valve chest l asheretofore described. To insure proper position ing of the valve memberl1 a spring latch, indicated at 50, is provided mounted at the end ofthe valve chest l5, which latch engages in V- shaped grooves 5| formedin the end of the valve member l1.

With respect to the feeding and proper mixture of the concentratedembalming fluid, a cup .55 is provided, which in the form shown,receives an upturned bottle or glass jar 56 of concentrated embalmingfluid. The fluid emptied into the cup from the jar passes downwardlythrough a conduit 51 and passage 58 to ports 58 and 60 in the pumpcylinder 33. These ports are arranged at the opposite ends of thecylinder and are controlled respectively by ball valves 6| and 62. Ports64 and 65 are also provided at the opposite ends of the cylinder 33which connect with a passage 66 which is in open communication with aconduit 61 connected at its other end to the valve 21. The ports 64 and65,where they enter the passage 66, are controlled respectively by ballvalves 18 and 1|. Inside the ball valves 18 and H, the ports 64 and 65are in open communication with ports or passages 12 and 13, which attheir outer ends communicate with the valve sleeve 43. Cooperating withthe ports 12 and 13 is a V-shaped communicationport 15 in the sleeve 43which according to its rotative adjustment, regulates the length of timethe ports 12 and 13 are in open communication with each other throughthe port 15 during the reciprocation of the valve sleeve 43. For thepurpose of rotatably adjusting the valve sleeve 43 the outer end of thevalve sleeve is provided with alongitudinal groove, indicated at 16,into which extends a spline 11 on an adjustable plate 18; The adjustableplate 18 is provided with a slot 1 8 through which extends a tap screw80 threaded into the valve chest 44.

It is to be noted that the diameter of the piston 35 in the cylinder 33is considerably smaller than the piston 25 inthe motor cylinder 22 sothat the water pressure moving the piston 25 is sufficient to cause thepiston 35 to move the liquid from the pump cylinder 33 through conduit61 to the valve 21 where, when the valve is in the position shown infull lines, the conduit communicates with a passage 82 in the valve andconduit 83 into the incoming stream of water through conduit l2, themixture there taking place constituting the fluid heretofore referred toas entering the cylinder 22.

Further explaining the action of the piston 35 in the cylinder '33, asthe piston moves in the direction of the arrow from its shown position,valve 6| is opened, valve 62 closed, valve closed and valve 1| opened.The fluid in front of the piston 35 is forced largely through port 65and passage 13 to the port in the valve sleeve, thence returned to theback of the piston through port 12 and port 64. The amount of suchsolution permitted to by-pass in the manner just described, regulatesthe amount of fluid that passes through passage 66 and conduit 61 to thevalve 21. On the return movement of the piston the operation of thevalves is the opposite to that just described, producingthe same effectof by-passing the large proportion of fluid from one side to the otherand pumping a small regulated amount to the valve 21 and thence to theincoming water heretofore referred to. As heretofore described, fluidfrom the cylinder 22 is discharged through conduit 26 to the valve 21.This valve 21 is of the rotative type and in addition to the port 82heretofore referred to, is provided with a port 85. This port 65, wheninthe position shown in full lines, provides open communication betweenthe conduit 26 and a conduit 86 which connects with the cylinder 34. Thefluid passing through the conduit 86, that is, water with the desiredproportion of the concentrated embalming solution mixed therewith, isthoroughly mixed in the cylinder 34 from which it is discharged througha connection 88 to a nozzle 88 in a glass container forming a pressureindicating chamber 98 ,which serves as a sight flow and pressure gauge.The inner end of the nozzle 89 is directed laterally and is providedwith an annular lip 9| so that the discharge of fluid or rate of flowthrough nozzle 88 is clearly visible. From the container 90 the fluid isconducted by means of a conduit or pipe 82 and hose 33 to an injectionneedle 94.

It will be understood that during the operation of pumping the embalmingfluid into the body that obstructions are sometimes encountered whichmust be met by proper regulation of the apparatus and it is for thispurpose that the glass container 90 is provided as by the level of theliquid therein, any rise in pressure would be immediately' indicated andif necessary the operation of the apparatus immediately discontinued.The

numeral 95 indicates a pipe or conduit connected to the valve 21 whichpreferably is provided with a hose connection not shown, to the sink orsewer.

It will be noted that by turning the valve 21, so that the port 85registers with the valve inlet of conduit 95 and with conduit 26, fluidfrom the cylinder 22 may be pumped directly into the sink. The samemovement of the valve 21 will bring the port 82, as shown in dottedlines, into registration with conduit 61 and a passage 96 which is inopen communication with the conduit 86. When this manipulation of thevalve has been accomplished the cylinder 22 and piston act only as apressure pump and it will be noted that straight solution from the pumpcylinder 33 is pumped directly into the mixing chamber or cylinder 34through the container 90 into the body undiluted by mixture of watertherewith. At this point it is noted that with an 75 apparatus soarranged other uses for the apparatus are apparent as for instance,concentrated solutions in the form of preservatives or curing materialsmay be injected directly intomeats such as cornbeef and that for suchpurposes the desired mixture may be produced by manipulation of theapparatus above described when the undiluted solution is not desired.

Means are provided for permitting automatic shut oil? of the apparatuswhen the desired amount of fluid has been pumped into the body. This isaccomplished by means of a ratchet wheel I mounted on a shaft ml whichis engaged by means of a dog I02, mounted on a shaft I03, the dog havingan extension in the form of an arm I04 which is adapted tobe engaged bythe flange 02 on the valve sleeve 43 when it reaches the end of itsstroke as shown in the drawing. :The arm I04 is so operated at theend ofeach stroke until the dog I engages the needle valve l3 moving the sameagainst thevalve seat I4 thereby shutting ofl the supply of waterunderpressure with a consequent stopping of the apparatus. The dog I05is mounted on the shaft IM and secured in adjusted position thereon bymeans of a nut I06. The dog is provided with markings, such as indicatedat I01, which designatemeasured,

quantities of liquids,such as pints or quarts, and by adjusting the dogon the ratchet wheel I00 with respect to an indication thereondesignated at I 08 the dog may be arranged to engage the,

valve I3 when a predetermined amount of liquid has been passed throughthe apparatus.
